Electrical Problems Need Help
1988 Mercedes 420 SEL ......gauges do not function, if you tap the multi function relay, part #201 821 00 47, the gauges will respond. I replaced the relay with a new one, however, the gauges still does not work. There is also a clicking sound in the drivers door. Any hint on what else could be causing this problem. Thank you.
